Air spring actuator for control valve

Time：2023-09-20

The air-powered air spring actuator is an innovative product independently developed by Sichuan Weika Company. It has won an invention patent and passed 1 million operating life tests and the type test of Zhejiang Special Equipment Research Institute.

The air spring is used to replace the mechanical spring output force and displacement, and the air-powered actuator is invented (invention patent number: ZL2016 1 0721714.0). Since its development in 2006, the product has been successfully used in many projects, and some projects have been in good condition for more than ten years. The product cleverly solves the disadvantages of the diaphragm actuator and the piston cylinder, has excellent application effectiveness, and has been successfully applied in the adjustment and switch control of the valve.

Advantages of air spring actuators

Small size, only 2/3 of the traditional pneumatic actuator

Light weight, only 1/2 of traditional pneumatic actuators

The output force is adjustable to meet the pressure of different working conditions

Allowed to use air pressure up to 0.7Mpa

Large output force and high mechanical efficiency

Compressed air reset, no mechanical fatigue, long service life

Accuracy up to 0.5%, small dead zone, high sensitivity

The positive and negative effects do not need to change the actuator, only need to change the air intake direction, and the maintenance is fast.
